GUIDE BAR AND CHAIN OIL The chain oiler provides continuous lubrication to the chain and guide bar. Be sure to fill the bar oil tank when you fill the fuel tank (Capacity = 6,8 fL oz.). For maximum guide bar and chain life, we recommend you use Craftsman chain saw bar oil. If Craftsman bar oil is not available, you may use a good grade SAE 30 oil until you are able to obtain Craftsman brand. The oil output is automatically metered during operation. Your saw will use approximately one tank of bar oil for every tank of fuel mix. Always fill the bar oil tank when you fill the fuel tank. FUELING ENGINE This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality 2-cycle air-cooled engine oil. We recommend Craftsman-brand oil. Mix gasoline and oil at a ratio of 40:1 (A 40:1 ratio is obtained by mixing 3.2 ounces of oil with 1 gallon of unleaded gasoline). DO NOT USE automotive oi! or boat oil. These oils will cause engine damage. When mixing fuel follow the instructions printed on the container. Once oil is added to the gasoline, shake container momentarily to assure that the fuel is thoroughly mixed. Always read and follow the safety rules relating to fuel before fueling your unit. • If engine does not stop, pull choke knob out fully.

See Chain Tension in the Maintenance section. • Cut wood only. Do not cut metal, plastics, masonry, non-wood building materials, etc. • Stop the saw if the chain strikes a foreign object. Inspect the saw and repair parts as necessary. • Keep the chain out of dirt and sand. Even a small amount of dirt will quickly dull a chain and increase the possibility of kickback. • Practice cutting a few small logs using the following steps. This will help you get the "feel" of using your saw before you begin a major sawing operation. • Squeeze the throttle trigger end allow the engine to reach full speed before cutting. • Begin cutting with the saw frame against the log. • Keep the engine at full speed the STARTING A WARM ENGINE entire time you are cutting.

Use a plumb orleveltodetermine thedirection of tree lean. • Weight and branches on one side. • Surrounding trees and obstacles. • Look for decay and rot. If the trunk is rotted, it can snap and fail toward the operator. • Make sure there is enough room for the tree to fall. Maintain a distance of 2-1,2 tree lengths from the nearest person or other objects, Engine noise can drown out a warning call. • Remove dirt, stones, loose bark, nails, staples, and wire from the tree where cuts are to be made. , ( Plan a dear retreatpath )..i_- Directionof Fall 45 ° FELLING LARGE TREES (6 inches in diameter or larger). The notch method is used to fell large trees. A notch is cut on the side of the tree in the desired direction of fall. After a felting cut is made on the opposite side of tree, the tree wilt tend to fall in the direction of the notch. NOTE: If tree has large buttress roots, remove them before m_.l<ingthe notch. NOTCH CUT AND FELLING TREE • Make notch out by cutting the top.of • the notch first. Cut through 1/3 of the diameter of the tree. Next complete the notch by cutting the bottom. See illustration.

During the low speed mixture adjustment recheck idle speed after each turn of the screw. The chain must not move at idle speed. Carburetor adjustment is critical and if done improperly can permanently damage the engine as well as the carburetor. If you require further assistance or are unsure about performing this procedure, call our customer assistance help line at 1-800-235-5878. Old fuel, a dirty air filter, dirty fuel filter, or flooding may give the impression of an improperly adjusted carburetor. Check these conditions before adjusting the carburetor. The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the following conditions: • Chain moves at idle. See "idle Speed" under adjusting procedure. * Saw will not idle. See "Idle Speed" and "Low Speed Mixture"under ad• justing procedure. , Engine dies or hesitates when it should accelerate. See "Acceleration Check" under adjusting procedure. * Loss of cutting power. See "High Speed Mixture H" under adjusting procedure. _There are three adjustment screws on the carburetor. They are labeled H, L, and T. They are located in the area just above the primer bulb. CARBURETOR PRESETS When making adjustments, do not force the plastic limiter caps beyond the stops or damage will occur. If carburetor presets are not needed, proceed to "idle Speed-T." Turn both m xture screws counterclockwise until they stop. -Tum the idle speed screw clockwise until it stops. Now turn counterclockwise 4-1/2 full turns. Start motor, let it run for 3 minutes, and proceedto the adjustmentsection, if engine does not start, refer to troubleshooting chart or call 1-800-235-5878. if engine performance is acceptable at the preset positions and there is no chain movement at idle, no further adjustment is necessary. ADJUSTING PROCEDURE idle Speed-T Allow engine to idle. Adjust speed until engine runs without chain movement or stalling. • Turn clockwise to increase engine speed if engine stalls or dies. • Turn counterclockwise to decrease speed. No further adjustments are necessary if chain does not move at idle speed and if performance is satisfactory. Low Speed Mixture-L Allow engine to idle. Then accelerate the engine and note performance. If engine hesitates, bogs down, or smokes during acceleration, turn mixture screw clockwise in t/16-tum increments until performance is satisfactory. Repeat this procedure as necessary for proper adjustment. After completing adjustments, check for acceleration and chain movement at idle. Reset if necessary. High Speed Mix_ture-H DO NOT operate engine at ful! _hrettle for prolongedpedods while making adjustments. Damage to the engine can occur. Make a test cut. Based on performance of the saw while cutting, adjust the high speed mixture setting in l/t 6-turn increments as foliows: • Clockwiseuntilsaw has good power in the cut wi_ no hesitation.Do notadjust by sound or speed, but judge by how well the saw performs in the cut. • Countemlockwise if the saw has speed, but dies in the cut or lacks power in the cut. After completing adjustments, check for acceleration and chain movement at idle. Reset if necessary. Acceleration Check If the engine dies or hesitates instead of acselerating, turn the low speed mixture adjuslment counterclockwiseuntil you have smooth acceleration with no chain movement at idle. Recheck and adjust as necessary for acceptable pedormance. 1,K / Prepareyour unitforstorageat the end tive in minimizingtheformation offuel ofthe season or if it willnotbe used for gum depositsduringstorage.Addstabi30 daysor more. lizer tothe gasolinein thefuel tankor fuel storagecontainer.Fellowthe mix WARNING: • Allowthe engineto cool,and secure instructions foundon stabilizercontainthe unitbeforestoringortransporting_ers.
